​Smart ADU Design & Casita
Construction by Coli Studio
Full-service ADU builders focused on affordable, high-quality casitas and small space living solutions.
At Coli Studio, we design and build accessory dwelling units (ADUs), casitas, and small homes that maximize space, value, and livability. Our team of ADU builders, designers, and permitting experts works with homeowners and investors to deliver turn-key projects with zero stress.
We serve families and property owners in Arizona and Florida looking for affordable modern ADUs, backyard cottages, or rental-ready small homes. With every project, we prioritize clarity, craftsmanship, and long-term value.
Custom ADU & Casita Design
Our team of small home designers creates efficient layouts tailored to your lot, goals, and lifestyle. Whether it's a rental unit, a guest casita, or an independent living space for family, we deliver functional, stylish designs.
Permit Management
Dealing with city permits can be time-consuming and overwhelming. We handle every step — from site plans to inspections — so your ADU construction stays on track.
Construction & Project Execution
We’re not generalists — we’re contemporary ADU builders with a streamlined construction model. We use trusted crews, quality materials, and project timelines you can count on.
Financing Support
Building a small home doesn’t have to mean draining your savings. We help you explore financing options, including equity-based loans and specialized ADU funding programs.
Full Project Management
From concept to completion, we coordinate all professionals involved — architects, contractors, inspectors, and suppliers. You get one point of contact and full transparency.
Post-Project Support
Even after move-in, we’re still your partner. We offer guidance on maintenance, repairs, and optimizing your new space for future needs.
